An odd attempt to explain the nuclear disaster to Japan’s small children

Chernobyl left about 6,000 children with thyroid cancer, largely because the children consumed radioactive milk, produced by cows allowed to eat radioactive grass. (Over 98 percent of those children survived.)
With word today that some milk, spinach and other produce in Japan is contaminated, what do you think of this approach?
I suppose poo is the most disgusting thing a 5-year-old could imagine, so perhaps this gets the message across. Still, it seems trite.
